MMAjunkie.com (www.mmajunkie.com) learned of the bout, which was first reported by MMAWeekly.com, on Wednesday evening from sources close to the event who said verbal agreements were in place with paperwork on the way.

UFC 123 is expected to take place Nov. 20 at The Palace of Auburn Hills in suburban Detroit, though the promotion has yet to officially announce the event.

It is unknown whether Griffin vs. Lentz will air on the televised portion of UFC 123.

Griffin is still under a medical suspension he received in the wake of his first knockout loss, which came just 64 seconds into his fight with former PRIDE champion Takanori Gomi at UFC on Versus 2.

It was a bitter defeat for the Xtreme Couture standout, who protested the referee’s stoppage despite a right hook that put him on the canvas face-first. He declined to shake hands with the Japanese star after pacing the octagon a few times.

Prior to that, Griffin was upset at UFC 115 by rising star Evan Dunham, who won the three-round fight by maintaining dominant position on the mat. The loss snapped a two-fight win streak.

Lentz, meanwhile, is coming off back-to-back wins inside the octagon and a heap of criticism from hardcore MMA fans. While he dominated his most recent opponent, “The Ultimate Fighter 9″ veteran Andre Winner, and earned a unanimous decision at UFC 118, many observers were not impressed by the fight’s lack of action, to put it mildly.

Still, Lentz has yet to fall short in the octagon with a January draw against Thiago Tavares serving as the only unusual footnote to his UFC career.
